9 Claims.

This invention relates to improvements in hair clipping devices; and themain object of my invention is to provide a clipper which shall beadapted for ready and accurate trim clipping of hair or bristles growingin the ears and nostrils. Further objects are to provide such clippersadapted to better facilitate trimming moustaches, beards and sideburns;to provide such a clipper of relatively small Size and which cannot outor irritate the skin; to provide a unitary clipper construction of thischaracter which comprises a lower stationary member and a reciprocatingupper member and each of the members having comblike side edges; and toprovide a device of this character which shall be simple in constructionand operation and relatively inexpensive to manufacture. A specialobject is to guard against occasion for piucking out nasal hairs by theroots and the possible consequence of dangerous infections.

Illustrative embodiments of this invention are shown in the accompanyingdrawings in which:

Figs. l0 and 1l are perspective views of the two forms described abovebut illustrating a manual operating means. These views are approximatelythe actual size of the clipper.

Fig. 12 is an enlarged cross-sectional view taken on the line I2-I2 ofFig. ll.

Referring to the embodiment shown in Figs. l to 4, inclusive, theinvention comprises a handle I having a power unit such as a motor orvibrator (not shown) of any well-known form, embodied therein, a lowerstationary skin contacting mem` ber 2, and an upper movable cuttermember 3.

The two members 2 and 3 are preferably constructed of a high grade oftempered steel and they are each provided with a comb comprising aseries oi slots 4 and 5 respectively, extending inwardly from the freeedges of said members to form teeth 6 and 1, respectively. The member 2is provided with a tongue 8 which is adapted to be inserted in theaperture 9 located in the end of the handle I, and secured therein byany suitable means such as by a set screw I0.

The cutter member 3 is also provided with an integrally `formed tongueIl adapted for insertion in the aperture I2 located in the end of handleI. The apertures 9 and I2 both lie in the same vertical plane. Theaperture I2 is only large enough tot readily accommodate the tongue I Iand provide for a free fore-and-aft lengthwise movement of the tongueIl. The tongue Il has an aperture I3 into which one` end of the powershaft arm I4 is adapted to seat. The other end of the arm is connectedto the motor or vibrator, not shown, located in the handle, foroperation by the motor, so that as it is repeatedly vibrated by themotor, the upper member 3 is reciprocated against the stationary member2.

The upper member 3 is also provided with an elongated slot I5 into whichis placed a bearing or spacer block I6 having an aperture I1 throughwhich the machine screw I8 is inserted for engagement into the threadedaperture I9 of the lower member 2. A bowed spring 20 is positioned onthe block I6 and member 3, and held thereon by the bearing head 2l ofset screw I8. As the spring is bowed downwardly so that the free 4endsof the same bear against the upper surface of member 3 it can readily beapparent that the member 3 will be positioned on the member 2 at alltimes for cooperation therewith. As the slot I5 is longer than thelength of the block I6 the member 3 is free to reciprocate against themember 2 at all times.

As will be seen from Fig. 3 of the drawings, the members 2 and 3 arearcuate-shaped in crosssection so that the outer ends of teeth 6--1 cometo a point at the side edges of the members to provide suitablecomb-like fingers into which the hair to be clipped may readily enterand be clipped by the reciprocating movement of member 3.

Referring to the embodiment shown in Figs. 5 to 9, the lower orstationary member 22 is formed from a blank and is punched or otherwisebent substantially in a U-shape with the bottom bulged outwardly and theside walls disposed substantially in a perpendicular plane as shown incrosssection in Figs. 'l and 8.

The upper or movable cutter member 23 is also bent in a substantiallyU-shape and is smaller in cross-sectional area than the member 22 as isapparent from Figs. 'l and 8. The member 23 is adapted to be placedinside the side walls of the member 22 and held therebetween by bolt 24which extends through apertures 5 in the side walls of member 22 andthrough the slots 28 in the side walls of member 23.

I'he members 22 and 23 are provided with tongue parts 21 and 28respectively, which function in the same manner and are secured to thehandle in the manner as tongues 8 and Il of the embodiment shown inFigs. 1 to 4 inclusive. Each of the members 22 and 23 is provided withslots and teeth 29--39 and 3l-32 respectively, and are identical inevery respect with the teeth and slots 6 7 and @-5 of members 2 3respectively. The member 22 is also'y provided with several elongatedslots 33 to substantially lighten the weight of the clipper.

In the embodiments shown in Figs. 10 and 11 the motor or vibratorillustrated in Figs. 1 and 5 is eliminated and a manual power meansprovided.

This manual power means consists of a pair of handle bars 3ft-35 eachhingedly connected at Saws? to an end block 38. The block 38 is providedwith a slot 3i) into which the tongle 2l is adapted to be inserted andsecured therein by any suitable means such as a set screw I in the samemanner as shown and described for attachment of the tongues 8 and 21 tothe handle I. The tongues il and 28' are especially elongated for use inthe manually operated devices of Figs. 10 and 11 so that the free endsthereof may be inserted through the slots l2 and be pivotally orotherwise secured to one end of each of the links lll of the handle bars3&5-35 respectively. The other ends of links 4E) are pivotally orotherwise secured to brackets 4i which are formed by striking out aportion of handle bars 34-35 and bending such portions inwardly at rightangles thereto, as clearly shown in Figs. l0 and 1l. A bearing l2 isprovided on the block 33 and a cooperating bearing or collar 43 issecured to the tongue 28 adjacent the: free end thereof. A compressionspring 44 is placed around the tongue 28 and between the bearings S2-d3.

It will be apparent that by applying inward pressure on the handle barsSil-35, the links di) will tend to force the inner member 23 outwardly,away from the bearing block 33, thereby reciprocating the teeth thereofagainst the teeth of the stationary member 22. Upon release of thepressure applied to the handles Sil-35 the spring i4 will tend to returnthe member 23 to its starting position. rIhe movement of the cuttermember 23 need be only a small fraction of an inch because of theminuteness of the teeth and slots of the cutter and stationary members.

It is to be understood that the prime numbers applied to Fig. 10correspond to like parts of the construction shown in Figs. 1 to 4inclusive and the numerals not primed applied to Fig. l1 correspond tolike numerals in Fig. y10.

Referring especially to Figs. to 9, it is to benoted that the two shearmembers or cutters, are Ll-shaped in cross-section, one being i'lxed`and the other slidable, and that they constitute substantially a pairof U-combs one embracing the other with their teeth disposed for mutualshear cutting.

It will be understood that some of the details set forth may be alteredor omitted without departing from the spirit ofthe invention as dened bythe following claims.
